how to attach multiple files to email client in android.
你好，
我无法发送包含多个附件的电子邮件。
这是我从网络和教程中找到的代码:
String[] mArray = getResources().getStringArray(R.array.pdf_entries);
int i = 0;
Intent theIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
theIntent.setType("application/pdf");
ArrayList<Uri> uris = new ArrayList<Uri>();
for (String file : mArray) {
if (booleans[i]) {
File fileIn = new File("/sdcard/mydir/"+file+".pdf");
Uri u = Uri.fromFile(fileIn);
Log.i("","** add: "+u);
uris.add(u);
}
i++;
}
theIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(theIntent,"Select email application."));
但我总是得到这个错误:
